Description

Technical Field

[0001] This utility model relates to the field of adjusting roller technology, and in particular to an electric mold opener for aluminum film. Background Technology

[0002] A search of existing Chinese patent document CN222120953U reveals an electric mold opener for aluminum film. The roller body is a multi-layered, nested roller. A hexagonal guide rail within a sleeve engages with a hexagonal bar to create a limiting mechanism, allowing the hexagonal bar to move only along the hexagonal guide rail. A screw inserted into the hexagonal bar forms a threaded connection with it, allowing the hexagonal bar to move along the hexagonal guide rail by rotating the screw while the sleeve is fixed. Therefore, in use, either the end of the sleeve or the end of the screw can be used as the fixed end. When the end of the sleeve is used as the fixed end, rotating the screw allows the hexagonal bar to move along the hexagonal guide rail. When the end of the screw is used as the fixed end, rotating the sleeve allows the hexagonal bar to rotate due to the threaded connection with the screw, moving along the hexagonal guide rail.

[0003] An electric aluminum formwork opener is a tool used in aluminum formwork construction. It is primarily used to safely, labor-savingly, and time-efficiently complete the formwork opening process, reducing labor intensity. It is particularly suitable for handling exterior wall joints and I-beam lines, significantly improving work efficiency. However, many existing aluminum formwork openers suffer from unreasonable specifications in various parts. For example, the solid hexagonal tube body, machined with deep holes, is uneconomical and heavy. The welded-in nut at one end of the hexagonal tube is insufficient in length, and the lead screw wears quickly, affecting its service life. Most importantly, the load-bearing bearing is a non-standard 35*25*7mm thick, easily damaged, and unsafe, leading to quality and practical defects in the aluminum formwork opener.

[0025] Example 1

[0026] Reference Figure 1-4An embodiment of this utility model provides an electric mold opener for aluminum film, comprising a sleeve body 1, a flat iron plate 2 provided at one end of one side surface of the sleeve body 1, a guide sleeve 3 provided at one end surface of the sleeve body 1, and a guide screw 4 provided at the joint between the guide sleeve 3 and the flat iron plate 2, a telescopic guide tube 5 provided on the inner side of one end surface of the sleeve body 1, and a reinforcing round steel 6 and a long screw 7 respectively provided on the inner side of one end surface of the telescopic guide tube 5, a lead screw 8 provided on the inner side of the other end surface of the sleeve body 1, and a transmission nut 9 provided at the inner end of the lead screw 8, and a center blocking nut 10, a force bearing 11, an inner retaining spring 12 and a drive nut 13 arranged sequentially from left to right on the outer end of the lead screw 8.

[0027] The sleeve body 1 and the flat iron plate 2 are connected by an inlay, and the welding length between the sleeve body 1 and the flat iron plate 2 is set to 40mm. The sleeve body 1 is set as a cylinder with a length of 200mm, a wall thickness of 4mm, and a diameter of 42mm. The flat iron plate 2 is set to a size of 130*30*12mm.

[0028] The flat iron plate 2 and the guide sleeve 3 are connected and fixed by the guide screw 4. The telescopic guide tube 5 and the reinforcing round steel 6 are inlaid and connected. The reinforcing round steel 6 is 20*55mm in size. The telescopic guide tube 5 has a wall thickness of 5-6mm. A guide groove with a length of 8mm and a depth of 5mm is provided on one side of the end of the telescopic guide tube 5.

[0029] The telescopic connecting rod and the long screw 7 are threaded together, and the long screw 7 is set to M16*30mm. The sleeve body 1 and the lead screw 8 are spliced ​​together, and the lead screw 8 is set to M16*200mm. The transmission nut 9 is spliced ​​together with the telescopic guide tube 5 and the lead screw 8.

[0030] The lead screw 8 is inlaid with the center blocking nut 10, the load bearing 11 and the inner snap ring 12, and the lead screw 8 and the drive nut 13 are threaded. The load bearing is set to the national standard model 6202RS#30*16*11mm, and the drive nut 13 is 25*35mm in size and has a hardness of 12.9 grade.

[0031] Specifically, its structure consists of a sleeve body 1, a flat iron plate 2, a guide sleeve 3, a guide screw 4, a telescopic guide tube 5, a reinforcing round steel 6, a long screw 7, a lead screw 8, a transmission nut 9, a center blocking nut 10, a load-bearing bearing 11, an inner snap ring 12, and a drive nut 13, forming an electric aluminum mold opener. The sleeve 1 facilitates hand-held operation during use. One end is fitted with the load-bearing bearing 11, and the other end is welded to the telescopic guide tube 5 for fixation. The flat iron plate 2 can hold the edge of the aluminum mold, allowing the telescopic guide tube 5 connected to the long screw 7 to be inserted into the diameter holes on both sides of the aluminum mold, thus enabling the aluminum mold to be separated and disassembled. The telescopic guide tube 5 facilitates transmission; the extended part of the telescopic guide tube 5 is locked with the long screw 7, and the other end is welded with an external hexagonal transmission nut 9 for external drive, working in conjunction with the lead screw 8 for lead screw transmission. The reinforcing round steel 6 bears the force... The hole facilitates the fastening of the long screw 7, which is transmitted through the central blocking nut 10. The transmission is achieved by welding the screw 8 to the central blocking nut 10, and the force bearing 11 is used for rotational force transmission. The inner retaining spring 12 is used to prevent the force bearing 11 from moving outward. The drive nut 13 drives the outer circle with left inner M16 and right inner four corners 2 / 1. With the help of an electric wrench, the overall length of the aluminum film electric mold opener is shortened and the weight is reduced. The size and specifications of the long screw 7 are reinforced, and the telescopic guide tube 5 and the external hexagonal transmission nut 9 are lengthened and hardened to improve overall stability. The specifications of the force bearing 11 are optimized, and the welding length between the sleeve body 1 and the flat iron plate 2 is lengthened. The guide screw 4 is a directional positioning screw, making the overall connection more solid and smooth compared to the existing mold opener, and less likely to fall off, effectively improving the stability of the aluminum film electric mold opener and increasing the mold opening efficiency of aluminum templates.

[0032] Working principle: The electric wrench is inserted into the drive nut 13 to drive the center blocking nut 10, the lead screw 8 and the force bearing 11 synchronously, and rotates the long screw 7 of the telescopic guide tube 5 to achieve frequent extension and retraction with a maximum stroke of 70mm. The aluminum film electric mold opener is a circular body composed of the sleeve body 1 and the inner and outer telescopic guide tube 5. The long screw 7 is hooked onto the side hole of the aluminum film by the outer circle and inner circle of the sleeve body 1 as guides and the reinforcing round steel 6 guide rail of the telescopic guide tube 5. An electric wrench is inserted into the drive nut 13 at the right inner four corners 2 / 1, driving the rotating connector center stop nut 10 and the load bearing 11. The other end of the center stop nut 10 is welded with a lead screw 8, which is connected to the telescopic guide tube 5 round steel pipe guide rail. When the electric wrench rotates clockwise, the telescopic guide tube 5 moves along the guide sleeve 3 to achieve in-and-out telescopic movement. The guide screw 4 positions the flat iron plate 2 against one of the two aluminum film sections, and the long screw 7 hangs on the other aluminum film. There is a 20mm diameter connecting hole on the side (the two aluminum films side by side have a cross section of 12mm and one is 6mm). That is, the flat iron plate 2 against one aluminum film section and the long screw 7 hangs on the round hole on the side of the other aluminum film. The electric wrench is inserted into the drive nut 13 on the center stop nut 10 and the lead screw 8 to separate the two aluminum films that are tightly attached to the concrete wall, making it easy to separate and disassemble.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
